"insulation"

We delve into Anna's inspiring rooflight replacement journey in her Hertfordshire home with a Vario by VELUX custom-made roof window. This stunning addition has wholly transformed her living space.At Vario by VELUX, we understand the importance of custom-made solutions to suit your unique needs, and our bespoke flat roof windows are designed to do just that. Anna's story is a testament to how our Vario by VELUX Rooflights can create a space filled with daylight, enhancing ambience and interior design.Custom Made Roof Window CollaborationAnna, who hails from South Africa and relocated to the UK almost 40 years ago, recognises the importance of natural light and how it can significantly impact your well-being. Having lived in her Hertfordshire home for many years, she knew it was time to replace her existing lantern rooflight due to a leak and a desire for a more modern design.When she reached out to her architect for guidance, he recommended Vario by VELUX, a decision that proved to be a game-changer for her home. Our team worked closely with Anna, making the bespoke flat roof window fit around the structural beam and seamlessly integrated with her living space. The result was nothing short of beautiful, highlighting the exceptional craftsmanship, professionalism and flexibility Vario by VELUX is known for.What improvements have you seen between the old rooflight and the new one?“The design of the extension is better now than when we had the previous rooflight. The lantern that stood up always bothered my eye and now this flat roof is unobtrusive. When I look out of my windows upstairs I don't see anything, I just see the garden, it’s just opened up another dimension.Another thing is the rain, the sound is different - it’s softer and I like the pool of water you can see lying on it - the different little patterns. It’s a wonderful sound and view so I really recommend it.”The Impact of Unlimited Daylight on Your HomeWith the Vario Unlimited Rooflight installed, Anna's living space now basks in abundant natural light. This daylight not only brightens up the room but also enhances the overall interior design. Even on cloudy days, the room remains well-illuminated, reducing the need for artificial lighting. The difference is undeniable, and Anna couldn't be happier with the transformation, stating, “I had such a good experience, everything was done so professionally… the end product is beautiful.”Advantages of Flat Roof Windows Over Lantern Roof DesignsWhen considering the choice between a flat roof window, like Vario Roof lights, and a lantern roof design, it's essential to highlight the benefits that make the former stand out:Unobstructed Views: Unlike traditional lantern-style skylights, flat roof windows can offer a more discreet and clean design that blends seamlessly with the roof. This design allows unrestricted views of surroundings, creating a more open and expansive feeling within a space. Lanterns can provide a beautiful and artistic effect by breaking up the daylight with the lantern intersections.Balancing Cost and Style in Skylights: Choosing between flat glass rooflights and lantern skylights isn't just about style but also cost. Flat glass rooflights are a bit friendlier on your wallet and can even help lower your heating bills, thanks to their excellent insulation. But don't let that sway you if your heart is set on a lantern skylight! They might require more time and expertise to install, but the result could be well worth it. Ultimately, the choice is yours - both options bring daylight and elegance.Ventilation: Vario flat rooflights are designed to maximise airflow thanks to our upstand, contributing to a well-ventilated and fresh interior space. Lantern roof lights, on the other hand, excel in aesthetics, adding a distinct charm to any room. However, their ventilation efficiency may not be as high as that of flat roof windows. Both options present a blend of form and functionality to consider.Insulation Differences: Lantern skylights and flat roof windows both provide insulation but to varying degrees. Lanterns with multiple glazing pane joints tend to have poorer insulation, leading to more heat loss. Conversely, flat roof windows, with fewer connections, generally offer superior insulation.There are certainly pros and cons to both types of rooflight design. What matters most is that you are considering adding more daylight into your your designs!Experience the ‘Wow Factor’ With a Bespoke Roof WindowAnna's advice when considering a renovation is crystal clear: "I really don’t think you can do an extension without a rooflight." She believes it's essential for well-being and making your space more enjoyable. A rooflight adds the "wow factor" that can genuinely make your life better.Incorporating a Vario skylight into your project can be a game-changer, just as it was for Anna.

Cardiff City Football Club has expanded into the new east Stand extension at Cardiff City Stadium. The expansion added a further 5000 seats to the stadium’s capacity followed by the addition of another 2,500 to 3,000 seats at each of the ends, raising capacity to a total of 38,000 seats, it also includes new corporate hospitality facilities. The stand is said to include plans for a concourse area on either side with a plush corporate area and catering facilities incorporated in the centre.Cellecta’s HEXATHERM XFLOOR 500 has been specified by Arup due to its high compressive strength insulation boards that were used under a concrete slab to comply with part L Building regulations.Lang O'Rourke was awarded this 350m² contract to construct this expansion.

One of the largest self-supporting display greenhouses in the world Following the renovation of the Grand Pavilion (das Große Tropenhaus, first built in 1906) at Berlin’s Botanical Garden, daylight enters through hundreds of small, heat-insulating yet highly light-permeable glass panes onto one of the world’s most significant collections of rare and endangered tropical plants. The inner panels used in the double-glazing for the overhead sections of the pavilion are made of laminated safety glass using stiff and strong SentryGlas® ionoplast interlayers. For the first time in Germany – following its “special approval” – a special “UV-transmissible” grade of SentryGlas® is used for this application, thereby sustaining the active growth of the plants and safeguarding their preservation

Location: Finchley, LondonSpecwall was used on the internal leaf of the cavity walls, with a brick tie system fixed directly to the panels, cavity insulation and brick outer leaf, as well as being used to accommodate the difficult curved façades. The installation of the internal walls at Beechwood Avenue needed to begin before the development was made watertight, necessitating a product like Specwall which can be used in all weather conditions. This enabled the required programme savings on the development which allowed it to proceed on schedule.Additionally, the site was constricted and external access was not available, requiring a wall system that could be built from the inside. Specwall satisfied this condition, and furthermore, the installation provided protection for the rest of the internal works to progress before the external masonry followed at a later date.

The proprietors of this domestic property in Harrogate added a large extension with a total roof area of 150m2. The client wanted the new roof sections to complement the slate work and aesthetics of the original building whilst adding a contemporary and stylish look to the extension.Originally considering a zinc sheeted roofing system, the client explored alternative materials that could achieve the same visual impact but at lower cost. After discussions with Cure Roofing Ltd, a Polyroof simulated metal finish was proposed as a roofing solution that would meet all the client’s requirements.Not only do Polyroof’s range of liquids offer cost savings over traditional metals, but they are also lighter in weight, totally seamless and can be pigmented to any RAL colour. Having no scrap value, the client also had the added peace of mind that the roof would not be a target for theft.A timber warm roof was constructed which incorporated 120mm PIR insulation to achieve a U-Value of 0.18 W/m2K in compliance with building regulations. An OSB3 TG4 deck was fitted above the insulation and Polyroof pre-formed GRP standing seam trims were fixed at 600mm centres into the deck. Next, the first coat of the Protec waterproofing system was applied over the whole roof area and encapsulating the standing seam trims. The roof was finished with a second coat of Protec pigmented to RAL 7016 providing an anthracite grey colour to the whole roof, accurately simulating the appearance of zinc roof sheets.The workmanship by Polyroof approved contractor Cure Roofing was second to none and the quality of the finish left the client delighted with their new roof. With BBA approval, top-rated fire performance and Polyroof’s trusted 20 Year Accredited System Guarantee, the client has total peace of mind that their new extension could not be better protected for decades to come.

The Proteus Waterproofing roof survey carried out found the existing flat roof system to be saturated. The existing roof build-up needed to be stripped back to the roof deck, with the main challenge of the roof refurbishment being the low up-stand heights available to the penthouses.The project required a flat roof system manufacturer involved at the initial roof survey and specification design stage, followed by the manufacturers technical back-up to assist with unforeseen and unexpected situations to ensure a successful installation of the new roof systems.High Performance WaterproofingThe terrace roofs above hated spaces demanded a waterproofing system with BBA certification. The fully bonded and seamless Pro- System® Plus was selected for its high performance and low odour, in conjunction with Proteus Pro-Therm Insulation to improve the roofs thermal performance and reduce the existing condensation risk.The flat roofs that were not above heated spaces required Proteus Pro-System® Plus low odour, seamless waterproofing overlay. Proteus Waterproofing worked closely with the Client and the Proteus Approved Contractor, which also acted as the Main Contractor, to ensure the installation complied with the specification design.Health & SafetySafety on construction sites is always of the utmost importance, as well as keeping disruptions to other trades to a minimum. Proteus Pro-System® Plus was selected for its high performance, low odour, phased cold installation and seamless waterproofing.Long Term Performance​Proteus Pro-System® Plus creates an elastomeric, seamless, cold applied waterproofing membrane. The Proteus Pro-System® Plus system can include warm roof insulation. The membrane does not become brittle with age, is BBA Certified with a durability statement of at least 30 years.

For the redevelopment of a former builder’s yard in Greenwich into a new build block of live-work units and residential flats, the developers were looking for a roof system which would offer long term waterproofing integrity, exceptional green credentials and enhanced aesthetics. The proposed green roof system would also reduce water run-off, create a wildlife habitat and help towards securing Code for Sustainable Homes Level 4.With a waterproofing system required to protect the concrete deck above the flats, a selection of cold-applied products were provided by Proteus Waterproofing that met the client’s requirements. The specialist contractor worked with Proteus Waterproofing on a specification which included the Cold Melt® inverted waterproofing system, Proteus Pro-Therm XPS and finished with a Proteus Pro-Living® green roof.Fast, hassle-free application The 500m2 Cold Melt® insulated Pro-Living® roof system was selected by the client and contractor for its ease of installation, cold application and all-round green credentials. After the pre-cast concrete roofing panels were craned into position, the joints were made good ready to accept the Cold Melt® inverted roofing waterproofing system. The inverted roof system incorporated Cold Melt® and Proteus Pro Therm XPS 150mm insulation. A Proteus Low-K Membrane was then applied prior to the application of the Pro-Living® green roof to complete the system build-up.Quality control Proteus Waterproofing worked in close partnership with the Contractor to successfully deliver the project to a very high standard within the required timeframe.Long term performance Incorporating recycled rubber-crumb and other organically grown products, Cold Melt® creates an elastomeric, seamless, cold-applied membrane and can outlast the lifetime of the substrate on which it is installed.

Rising 143 metres in the London skyline, this 42-storey tower located in Stratford near to the former Olympic park, consists of 248 luxury residential lofts and a 145-bedroom hotel.Designed by high-rise specialist architects Skidmore, Owings and Merrill, over 17,000m2 of ipasol Light Grey 60/33 glazing was chosen for the facade thanks to its aesthetic of a light grey tint when viewed from outside but highly transparent and neutral when viewed from interior spaces.As the facade includes full height glazing, a combination of solar control and thermal insulation coated glass was needed to allow the facade to achieve its energy efficiency targets. Some glazing types also utilise acoustic laminated glass to maximise the sound reduction properties of double glazing units.

Despite the challenges posed by completing construction and opening during the first lockdown, the new Skelton Lake Motorway Services project opened in March 2020 as planned, providing essential services to hauliers and key workers travelling during the start of the pandemic. The project incorporates an extensive green roof build-up to minimise the visual and physical impacts of the development on the surrounding country park and to enhance the biodiversity of the project.The wildflower green roof design provides multiple environmental benefits; including provision of a new habitat for local insect and bird life, helping to lower the site’s carbon emissions by absorbing heat emitted from the building into the cooler roof surface - reducing the air conditioning demand in the summer months. The green roof build-up also provides a level of insulation against heat loss in winter. 

Chosen in a riven textured finish and in Iceberg, Bordeaux and Basalt colours to create symmetry in the building’s decorative facade, the high quality of each Carea cladding panel creates a stylish finish which met the architect’s vision. In addition special vent tiles were specified which were used above the windows and for kitchen extracts to create an invisible way of creating ventilation for the building.Each of the riven panels were installed by OCL Facades using innovative grooves at the top and bottom edges to create a seamless finish. As well as an efficient secret fix installation process, Carea cladding panels provide several performance benefits. Offering a high degree of insulation, they will play a pivotal role in the development’s thermal efficiency, thereby lowering its heating needs and aiding sustainability.

The world’s premier destination for design and decoration excellence. Home to 120 showrooms and over 600 of the world’s most prestigious luxury brands, it is the largest of its kind in Europe.Willmott Dixon is a privately-owned construction and interior fit-out specialist with the ambition to create a huge and lasting positive impact on society, the main contractor who hired us to meet their client’s project specifications. The product selected for the project was the Soundis Absorb-R GypLine αw (also commonly known as a Seamless Monolithic Acoustic Spray Plaster System) which is an extremely flexible seamless sound absorption system. It is a non-perforated, monolithic system consisting of a mineral fibre panel with a layer of micro-porous plaster. Excellent Sound Absorption was required at this project and therefore our task was to ensure class A sound absorption within the large atrium. The Absorb-R GypLine αw was used as a seamless high performing sound-absorbing system, a system with excellent eco-credentials. The GypLine αw insulation board also benefits the energy performance of any building by enhancing the insulation of the building envelope.We were challenged with working almost 20 meters above the floor which adds difficulties to any installation but nothing we haven’t overcome before in previous projects. Absorb-R GypLine αw was selected as the finish offers unrivalled levels of sound absorption but also ensures walls and ceilings are clear of panels and visible acoustic solutions, providing a virtually seamless monolithic surface for walls and ceilings in a choice of RAL colours. This seamless and complete solution can be adapted to a wide range of rooms, from home use, office space to conference halls, auditoria, theatres, recreational sports and educational areas. The Absorb-R GypLine αw acoustic system is environment-friendly, fully recyclable and has natural components that offer optimal sound absorption with extensive resistance to fire.

The Darwin Centre cocoon creates a new architectural icon for the capital, ground-breaking in scale and breath-taking in its originality and creative brilliance.The design features a vast free-standing structure taking the form of an enormous cocoon within a glass atrium. The eight storey high cocoon houses a unique collection of 17 million insects and 3 million plants collected over the last 300 years by scientists including Charles Darwin, Alfred Russel Wallace and Sir Hans Sloane. The building completes the Museum’s life science complex, the Darwin Centre, following the first phase opened in 2002.Design TeamThe response of the architectural design team at C.F. Møller, lead by partner Anna Maria Indrio, was to create an engaging image reminiscent of an essentially organic form. The surface and texture also needed to reflect this, so the subtle sheen of the ivory coloured Armourcoat plaster was chosen. With an intersecting network of ‘silk threads’ that criss-cross the cocoon, the surface allows for movement and provides a visual framework for openings and niches. Armourcoat was specified to devise a unique creative solution combining both the insulation and the final decorative layers. The cocoon performs a genuinely protective job providing thermal mass to inhibit any fluctuations to the internal temperature – essential for the museum’s treasured specimens. The structure also houses state-of-the-art laboratories for 250 international scientists and an interactive visitor exhibition.ConstructionA sixty-five metre long skeletal structure was built by sprayed concrete specialist Shotcrete – the first above ground sprayed concrete structural element in the world. Expanded metal mesh was fitted to the steel re-bar framework and a 250mm thick layer of concrete was spray applied to create a 3,500 m2 raw concrete surface. Armourcoat then applied a resin modified render to the structure to minimize localized variations to the surface, before the polystyrene insulation layer was fixed. Using Dryvit Genesis adhesive and over 16,000 Hilti insulation fasteners, a 50mm polystyrene layer was fitted to the entire surface of the cocoon then covered with a layer of reinforcing mesh bedded into Dryvit Genesis basecoat. To create the silk threads wrapping the structure, a special cutting machine was devised which could cut an accurate slot and create the individual 340 panels which make up the cocoon surface. A total of 5.6km of edge bead was then fitted before Armourcoat’s unique AntiCrack substrate preparation system was applied. AntiCrack is a polymer and fibre modified gypsum skim-coat plaster which creates a first class substrate, keeping the Armourcoat plaster layer in peak condition. Two layers of Armourcoat keycoat were applied prior to the application of the final finish. The finished effect of a giant silk cocoon was achieved using ivory coloured Armourcoat Armuralia polished plaster - an exquisite, smooth finish with subtle tonal variations.The cocoon is a milestone achievement, a unique design and technical solution befitting the historic and social reference of the Natural History Museum. This also is a stunning example of the type of commercial projects now undertaken by Armourcoat, celebrating twenty-five years of creative excellence in 2009.Client: Natural History MuseumArchitect: C.

Project: 1 Aylesbury Street, Clerkenwell, London, EC1R 0DRClient: MeritcapeArchitect: Atum Design LabM&E consultant: EngDesignProtecting Cities Against Fire with Advanced GlazingDaylight-flooded spaces command a premium from tenants, but in the densest urban areas – where buildings are very tightly packed – it can be difficult to achieve. Not least because of the need to protect against the spread of fire.This was the challenge for developer Meritcape when they set out to refurbish 1 Aylesbury Street – a converted historic warehouse building in Clerkenwell, East London.The designers wanted to fill every floor of the building with natural light, from both the front and the back of the building by using floor-to-ceiling glazing on every floor. However, the rear of the property was just three metres away from a neighbouring building.To prevent fire spreading from one building to the next, building regulations specify the fire resistance that external walls need to be able to provide. This is given as minimum requirements for integrity – how long they can contain smoke and flames – and insulation, or how long they can prevent the escape of heat. Steve Bond, technical and customer support manager, fire, at Pilkington United Kingdom Limited, said: “When you have two buildings this close together, standard glazing is not an option, as it doesn’t put up enough of a barrier to fire spreading outwards from the building.“That’s where fire-resistant glazing can make a big difference. By providing protection against fire while also letting light flow in, we can create light-filled spaces in very built-up parts of the city where not long ago it wouldn’t have been possible.“As well as sealing in flames and smoke for at least an hour, the glass also provides radiation shielding that reduces the amount of heat energy that can pass outwards through the glass – another key means of spreading fire.” The rear façade of the building is glazed in Pilkington Pyroclear® Plus insulating double-glazed units, delivering not only the right level of fire resistance, but have also been designed to give excellent thermal insulation (U-value) properties to reduce heat-loss from the building.Davood Kiani, Senior Project Consultant at Meritcape said: “Those looking for modern commercial space expect floorplans to be well lit with natural light, and this is one of the main design challenges when working with buildings in the most densely urban areas of the city.“Fire regulations are one of the big reasons for this, so Pilkington fire-resistant glazing means we can achieve the best of both worlds - a building that meets or exceeds all of the safety regulations while also feeling spacious and airy.”A total of 800 m2 of Pilkington glass was used in the project, including in the front façade of the building, in which hundreds custom-sized small double-glazed solar-control units were used to imitate the crittall steel-framed windows that are a signature feature of buildings in the area.Images by S G Photography

Urban development within St. Helier, the capital of Jersey is gathering momentum with URSA seeing its specialist insulation products specified at one of the capital’s newest and most ambitious developments. The largest of the Channel Islands, St. Helier is a lively harbour town and has become one of the UK's most popular tourist attractions, creating a high demand for ongoing residential and commercial development. Both its commercial port and marina, as well as the centre and the main neighborhoods, are undergoing an in-depth study for the renovation of its building stock and the transformation of the urban landscape it offers. The ultimate objective is a profound urban regeneration carried out through the creation of a commercial heart open to the sea, in the city centre, and modern, sustainable and healthy residential developments on the outskirts to ensure the demands of future growth. It also aims to reduce traffic and create a walkable city for pedestrians and cyclists with green spaces and open spaces. In the north of the city is Ann Court, a large development located next to a large municipal park built on the site of a former car park that has been demolished. Being developed by Andium Homes, construction is nearing completion on the development of 165 new homes of different sizes and orientations (with internal and external courtyards), but with a common standard: the energy efficiency and sustainability of the whole complex. To support the sustainable objectives, architects have specified a ventilated façade that guarantees thermal and acoustic comfort, whilst preventing moisture penetration and condensation. A correctly designed ventilated façade system also guarantees a fire safe structure, prolongs the life of the building and enhances its energy efficiency. As part of the specification, 2,400 square meters of 220mm URSA Walltec Black 32 were specified. The choice of material was the direct decision of the architect Stephen Marshall of Axis Mason Architects, who decided on the glass wool slabs after learning about their performance and the knowledge provided by URSA's technical office. URSA Walltec Black 32 is a semi-rigid glass wool slab treated with a water repellent additive. The slabs have a black glass fibre tissue to one side only that helps to hide the insulation in ventilated façades with open joints. It is a non-combustible product that does not contribute to the spread of fire, is water repellent and has high performance to ensure the thermal and acoustic comfort of the entire residential complex. Once the insulating material has been fixed, the façade is completed with the installation of the cladding to create cavity that ensures the properties of the system. This imposing façade enveloping the courtyards of Ann Court facilitates a new building in the north of St. Helier where social interaction, tranquility, quality, comfort and healthiness are guaranteed.  Ian Claydon, URSA UK Technical Manager, said: “We first became involved in this scheme in June 2020. We were approached by the architect for recommendations on correct choice of product and the thermal assessment for the external walls.  “During the early stages of the project, we were in regular contact providing advice on the target U-value in the wall(a commendably low 0.18 W/m2K), as well as the impact on Jersey SAP energy assessment and the technicalities of rainscreen cladding. The team were particularly impressed with the speed of response and our wider technical knowledge, helping to support the perfect specification.” 

Fulham is the oldest of the ten London Premier League football clubs. Founded in 1879 by the Reverend John Henry to offer the young workers of the neighborhood an alternative to less healthy temptations, since 1896 it has had its home in the mythical Craven Cottage.The site and the club have evolved dramatically since. Located on the banks of the River Thames, very close to the refined London neighborhoods of Chelsea, Kensington and Chiswick, the stadium is one of the main tourist attractions of the London capital due to its significance in the history of football, and its extraordinary location on the banks of the Thames.The south-western part of the British capital is now undergoing an ambitious redevelopment plan that includes the demolition and new construction of the legendary Riverside Stand, adjacent to England's most important river. The scheme is being led by the club itself, appointing Buckingham Group as main contractor and Populus as its lead architect. As part of the wider scheme, an URSA specification has been made to ensure all thermal and acoustic targets are met. The project will see the redevelopment and expansion of the current Riverside Stand to increase its capacity from 4,689 to 8,650 whilst increasing the overall capacity of Craven Cottage to 29,600 seats. Creation of a new public riverside walk as well as new restaurants, cafés, bars, corporate hospitality and event space forms an important part of the scheme. Below ground, a new basement will provide ‘back of house’ facilities, club and lounge area whilst nine serviced apartments will be made available on site.Partnering with distributor, Encon and liaising directly with the installation team at Grant Plastering, the project used URSA TERRA glass wool slabs to insulate the ceilings and soffits. Normally used behind rainscreen cladding systems, URSA WALLTEC 32B was chosen because of its class leading thermal conductivity of 0.032 W/mK, acoustic performance and ease of installation.In addition to the low thermal conductivity, the slabs have exceptional acoustic absorption and are non-combustible (Euroclass A1), so they do not contribute to the propagation of fire, an advantage that is fundamental in an installation of this type, designed to house thousands of people.Another noteworthy aspect is the sustainability that they bring to the buildings in which they are installed, and which are recognized by the most prestigious European certifications. URSA's range of glass wool insulation products are completely recyclable and use less energy in their manufacture, transport and installation. Ian Claydon, URSA UK Technical Manager, commented; “This is an incredibly important development for the capital that sees a huge amount of investment in one of the UK’s oldest football clubs. The site location and wider ambitions of the project make this an incredibly exciting development to be part of.“We have worked closely with the project managers technical team and installers to ensure they made the very best specification. Opting for one of our core products, we have managed to fulfil all of their wider needs in terms of the insulation specification.”The works will include an increase in capacity and new amenities, but also seek to enhance the space for residents, fans and tourists, with a public promenade running along the banks of the Thames, commercial spaces and new meeting rooms underneath the grandstand.  

When CMS Danskin Acoustics Limited was engaged by Progressive Group to ensure the Shangri-La Hotel’s 42 floors in the Shard were effectively soundproofed, it wasn’t a straightforward assignment. From the very first sketches drawn on a napkin by Piano during dinner with entrepreneur and property developer Irvine Sellar, the Shard was always intended to be ‘all about the windows’, with expressive façades of angled glass reflecting sunlight and the sky, and affording 360° views of the city.Unfortunately, when the glazing is central to the design, floors can get in the way of the overall effect, and the temptation is to minimise floor heights (within Building Regulation parameters, of course). This presents a significant challenge to acoustic insulation installers. In short, the thinner the floor, the harder the soundproofing material has to work acoustically and the more physical punishment it has to endure.For approximately 70% of the floors, Progressive applied a Gyvlon liquid screed at a 40mm minimum thickness. The screed was pumped from ground level, with the largest pour in excess of 80m3 covering an area of 1,680m2. In approximately 30% of the floor areas, however, the floor screeding level could not be raised because of the existing floor-level transom in the curtain walling. This meant that there were instances of screed thicknesses of approximately 25mm in places.CMS Danskin’s Regupol E48 (REGUPOL sonus curve 8) was specified, a Robust Detail approved (E-FC-6) high-performance screed isolation material. E48 (REGUPOL sonus curve 8) was perfect for those ‘thin screed’ areas, with its maximum load bearing capacity of 3000kg/m3 (30kN/m2), combined with a mean average impact sound insulation performance of 46dB and a mean average airborne sound insulation performance of 49dB, both values well in excess of the requirements of Part E of the Building Regulations.Building Regulations aside, E48’s (REGUPOL sonus curve 8) ‘over-performance’ is crucial for a hotel as exclusive as the Shangri-La. The award-winning, globe-spanning hotel group prides itself on providing a customer-focused experience, with the emphasis very much on luxury. Intrusive noise from above or below a guest’s accommodation would almost certainly undermine those efforts. Plus, with this being a flagship project for the Shangri-La – their first hotel in Europe – ‘fit for purpose’ simply wasn’t an option.As a Robust Detail underscreed, E48 (REGUPOL sonus curve 8) has already been rigorously pre-tested to ensure it achieves a minimum performance of 5dB over and above Part E, thus eliminating the need for Pre-Completion Testing. However, CMS Danskin and Progressive, having worked together successfully on the exclusive One Hyde Park development, preferred to adopt a partnership approach, with the emphasis on planning and testing, giving absolute certainty to all parties and making full use of all the skills, expertise and experience at their disposal. To this end, Paul Absolon, CMS Danskin’s Technical Director, worked closely with Progressive’s technicians, carrying out off-site simulations and fitting trials with varying screed thicknesses. Only once both parties were satisfied with every aspect of E48’s (REGUPOL sonus curve 8) acoustic performance in a ‘real world’ situation did the installation proceed.More than 16,000m2 of E48 (REGUPOL sonus curve 8) were installed over approximately 3 months, with Progressive and CMS Danskin maintaining their close working relationship throughout.Tony Cooney, Estimating Manager at Progressive Group, said, “The completion of the screed and insulation work on the Shangri La Hotel development was a fantastic achievement and it presented a number of very challenging situations – both technical and logistical. Solutions to these challenging situations are achieved by the co-operation of all parties involved – including material suppliers. The technical assistance provided by CMS Danskin on this Shangri-La project and other prestigious contracts in the London region in recent years has been exceptional and we look forward to continuing our excellent relationship.”Said Paul Absolon, “It was a privilege working on a project as ground-breaking and culturally significant as The Shard, and it was a pleasure working with the professionals at Progressive Group again. At CMS Danskin, we like to be put to the test. The Shard certainly was a challenge and we’re proud to have met that challenge and delivered.”

From the beginning, architects DLR Group designed Metea Valley High School in Aurora, Illinois, to light up education, both literally and figuratively. The sprawling campus with room for 3,000 students is broken down into a handful of more intimate, human-scale learning spaces, called “think tanks”, where interaction with faculty is encouraged. Two interior courtyards, open to the sky, offer fresh air during free periods. Shaped a bit like a bow tie, Metea combines three concepts – mind, in the midsection, and body and soul on either end – to offer students a truly 21st century school experience.Lighting up Metea in the literal sense comes largely from the extensive use of Kalwall translucent curtain wall throughout the school. Upon coming through the school’s main entrance, visitors are struck by the cheerful, airy, daylighted lobby. Controlled daylight also pours into the school’s innermost areas, traditionally a structure’s darkest, from the courtyards. Kalwall introduces daylight into the vast commons area that serves as the students’ lunchroom. In the gymnasium, Kalwall’s shadowless, glare-free light enhances ball handling in team events; sunlight does not glance off the shiny court surface. The diffuse-light-transmitting panels also prevent glare off computer screens, easing eyestrain. And in a dramatic demonstration of Kalwall’s superb flexibility, the design includes occasional, narrow, horizontal runs of clear glass – some serving as clerestories – adding visual interest as well as clear views to the outside.At 464,000 square feet, Metea could have been an energy-consumption nightmare, adding significantly to its $125 million total project cost. But innovations such as demand control ventilation, energy recovery wheels, and high efficiency boilers will save Indian Prairie School District 204, the state’s fifth largest, thousands of utility dollars every year and pay for themselves in just a few years. In fact, the building’s design is targeted to be 19 percent more efficient than ASHRAE 90.1 requires. Because translucent Kalwall admits so much controlled daylight, the school’s exterior light harvesting system, which monitors indoor light levels, can actually turn off electric lights in public spaces automatically when they are not needed. The harvesting system alone is expected to save the district over £16,000 a year in operational costs with a payback of under seven years.Illinois can get very cold in the winter and quite toasty in the summer. Highly insulating Kalwall helps there, too, keeping temperature extremes outside and lessening the need for and cost of heating and cooling. During the manufacturing process, standard 2-3/4” and optional 4” Kalwall sandwich panels can be infilled with various densities of specialized, translucent insulation. Architects and designers can achieve a thermal insulation value of up to R-20 (0.05 Btu/hr/ft²/F).At Metea Valley High School, DLR Group chose to include Verti-kal™, a unique design variation on the standard shoji or square grid layouts of Kalwall Translucent Systems. The panels incorporate internal, continuous supports to provide a vertical emphasis. As with all Kalwall translucent systems, Verti-kal distributes diffused daylight throughout the school, even on cloudy days, drastically reducing the amount of artificial lighting required and eliminating shadows and glare as well as stark contrasts of light and shade. Verti-Kal can be supplied in panels up to 5 ft. (1.5 m) wide and up to 12 ft. (3.6 m) high, minimizing the number of joints. The unique format creates an entirely different look while still utilizing the most highly insulating, diffuse-light-transmitting, structural composite technology.Any school system must concern itself with maintenance costs, and Kalwall excels there as well. The panels are vandal-resistant and self cleaning; dirt simply washes off with each rainfall. After dark, the diffuse, translucent properties of Kalwall contain interior lighting and prevent direct-beam light pollution. Instead, the exterior surface of the building simply glows beautifully, boosting Metea Valley High School’s aesthetics and welcoming both students and the surrounding community to a true masterpiece of daylighting.Photography: James Steinkamp

Croft Gardens is a four building student accommodation at King’s College in Cambridge, achieving full Passivhaus Classic standards. With 12 rooms across three floors of three crescents and a villa, along with the Victorian Holmcroft building which provides a library, laundry room and common room area, Croft Gardens provides 84 homes for graduate students. Including graduate rooms, communal facilities, landscaping and external works, Croft Gardens will be carbon negative for the first 7-10 years of operation.Cellecta’s HEXATHERM XFLOOR 500 was specified by Feilden Clegg Bradley due to its high resistance to compression and closed cell structure that provides unrivalled resistance to water absorption, making them ideal for residential applications. These insulation boards are used under a concrete slab to comply with part L Building regulations.Gilbert-Ash was awarded this 650m² contract for this development at Barton Road.

The ChallengeA new development of 15 individually designed four and five-bedroomed homes set in over four acres of mature woodlands in Nottingham.Each home in this secluded development was to be built over three storeys and designed and styled with the latest contemporary finishes, both inside and out. With a gated entrance, the private development is set down into its own valley, but still has breath-taking views of the city.The SolutionForterra’s Mandarin Mixture and Yorkshire Red Blend Butterley Bricks were chosen to meet the development’s high specification requirements. The properties were economically designed with underfloor heating, air source heat pumps, and a high level of insulation to keep running costs down.The BenefitsIncluding the latest interior finishes, each home also offers something different, from cinema rooms to beautifully landscaped terraces.

The Handball Arena in the Olympic Park in the centre of London is an iconic landmark - designed and built to host the handball events at the London Olympics in 2012, it is now a completely flexible arena which hosts a range of different sports and training events.Main contactor Buckingham Group enlisted IRC Carocelle to carry out the roof works, and IRC Carocelle turned to Fixfast to supply the complete fixing package for this - our tube washer and fastener combinations enabled the use of panels which achieved the specified insulation levels.Fixfast also had the needed solution for the external façade - thousands of shingle cleats were used to hang the 3000sqm of specially manufactured copper panels."Fixfast maintained a high level of quality throughout the build, minimising site wastage and ensuring continuity of work for the site team"Steve Holder - Owner of IRC Carocelle

Ancon STC Steel-to-Concrete Insulated Balcony Connectors have been chosen to securely connect over 1000 bolt-on steel balconies at London’s ground-breaking Embassy Gardens Phase 2 development.Sitting alongside the new American Embassy on London’s South Bank, Embassy Gardens is the centrepiece of one of the Capital’s biggest ever regeneration projects. Phase 2 of the project is delivering a total of almost 900 luxury apartments across three stunning 21-storey glazed towers, traditionally brick-faced to reflect the area’s industrial heritage.Characterised by large modern balconies with views over the surrounding linear gardens and river beyond, the towers are linked together by a raised podium garden and feature a world-first transparent outdoor pool, 35 metres up, allowing residents to swim between the tenth floors of two towers.

Valette Square is a community of 33 mixed 2, 3 and 4 bedrooms townhouses with private gardens and terraces, built in Salford’s historic centre. Developed by @buttressarchitects , it was designed to introduce new homes to the area, create easy links to nearby areas and for community spaces to exist where possible.The area is named after Pierre Adolphe Valette – a French impressionist who taught the local painter L.S Lowry, and taught at the Manchester Municipal School of Art. The local existing Georgian aesthetics were echoed in the development with Floren’s Brunello bricks being selected for their tones and subtlety, leaning towards nearby red brick buildings.Amongst numerous sustainable efforts, the townhouses’ façade and positioning make the most of natural daylight to reduce the amount of artificial lighting needed, improved insulation and smart heating systems.Valette Square was shortlisted for the Housing Design Award in 2020
